The cam body-4S is pivotally "supported bya suitable stud or shaft 52 and shaft 52 V may-.bevsupported bystrap-like member 38,

for example by meansofcross-piece 53 car= 'ried by member 38. The body of cam 48 is U'shape-anda fiat" springfit is disposed be tweenthe arms thereof and. theends of the spring contact the lower edge of the strap member 38; The ends of the spring 54: may

be angular andmayproject upwardly over the outer face ofthe strap member 38. The springyleldingly holds th cam in a position 7 in which thecam-is inoperative for actuating the rod 44 and stud 5.1. The'cam body 4-8 carries a stud or shaft Sn shaft 55 is supported a trip finger 56 carrying a lug 57-that may bemoved into the pathaof the pins 87. A spring 58 yield ingly holds the linger in such normal position wherein the lug 57is disposed out of the path of the pins 37. Y i The'trip finger ducing the lug 57 inthe path of pins 37, by

means of stem 59, carried by the armature '60 of electromagnet 61. Normally theelectromagnet is deenergiz ed, and the spring 527 holds'thearmature at a distance'from the core 62 of'the electrom'agnet. The stem 59 may extend reciprocally through the core 62. The

. stem 59 may be manually actuatedfor trip ping the device by manual depression of armature 60.1. End63 of the electrom nct winding may be electrically connected with ai'iy suitable source of electrical energy, not. shown'.-. If'a motor 1s used to operate the wr1nger,'the end63 may be connected with T the'source of energy used for the motor, other- "wise a batterymay be connected. to end 63.

End 64= of the windingis electrically con: nected to aswitclr65 that may be mounted on the topmember 66 ofthe frame. 10. Other 7 may beactuated for intro switches may be provided in parallel with switch 65 and may be so positioned that an operators foot, knee or other part of the body may be used to close the circuit through the electromagnet, should the operators hands be caught between. the wringer rolls. The conductor 67 leaving the switch is connected with the source ofelectrical energy. j v

The switch 65, shown herein, is one that may be closed by blowing breath against same. In those instances where an operator might have both hands caught between the rolls,,the operators head would be rather close to the top of the device and therefore the operator could release her hands by merely blowing against a diaphragm 68, suspended by a lightly tensioned spring 69, and

7 thereby efiecting contact between contacts 7 0' and 71. Adjustment of the gap between con- ;tacts 70 and 71 may be effected in any suitable manner and withany means commonly used for such purpose. The casing 72 of the switch may be mounted on the top member in any suitable manner and may be so adjusted that the diaphragm may be actuated from any direction. If desired, a plurality. of similar switches, fixed 0r adjustable relative to the frame, may be provided. Preferably the diaphragm, in its normal position, closes the opening 7 3 in the truncated conical plate 74 of the device, and air gaps 75 are provided about the diaphragm, at the rear of plate 74, whereby to obviate building up of pressure at the rear ofthe diaphragm that might hinder free and 'easy operation of the switch.

The cross bar 31 may be depressed by means of a suitable lever 76, pivoted-in a suitable aperture 77 provided through the top member 66. The lever serves to simultaneously engage both lugs 41 with their respective catch members, and the tripping of the finger 56 by any of the pins 37 servesto oscillate the cam 4:8 whereby to simultaneously release both lugs 41 from their respective catch members.
